Sometimes God keeps us awake, or randomly wakes us up at night to pray for friends, enemies, anyone or anything. He even gives us spiritual dreams to tell us what we're supposed to pray for, that's awesome.
A prayer for uncertain moments based on 1 Thessalonians which tells us that God makes us holy and keeps us safe. His peace alone removes all blame and condemnation. Let your faith in Christ cast away all uncertainty in your heart.
